Watering regime influence on sustainability of floristic structure of special nature reserve “obedska bara

Abstract

Obedska bara is the greatest flooded area of the river Sava in Serbia and one of the oldest protected natural ares in the world (protected since 1874). It is remain of the left riverbed of the river Sava. The main feature of this area is mixture of different types of wet sites (puddles, swamps, wet meadows, hygrophilous forests, etc.) that are occupied by different plant and animal species of a great national and international importance. Research in this nature reserve is related, before all, to influences between surface waters of the river Sava and Obedska bara on groundwater regime at wider area of this locality. Regime of fillfulling and emphasis of the water defines biocenosis development of this ecosystem. The research is related to period between 2002 and 2011 (10 years long) and obtained results define the state of this aquatic ecosystem.
